The Bay Area's Top Rated Shingle Preservation
Extend Your Roof's Life by Up to Ten Years per Application
North-facing roof pitches across Santa Rosa collect algae and lichen faster than most homeowners realize. Wet winters saturate those surfaces, and the oak and redwood canopy common throughout Sonoma County keeps shaded sections damp well into spring. Left alone, that biological growth breaks down asphalt shingles and accelerates the timeline toward a full roof replacement.
We are the only company in California authorized to sell and apply Bright Green Roof Shingle Preservation, a proprietary, USDA-approved treatment that adds up to ten years of protection per application. At Ferretti Softwash, we apply it after a thorough soft-wash roof cleaning, sealing the surface against the regrowth cycle that leads to premature aging. The treatment works on asphalt shingle roofs of all ages, whether the roof is relatively new or has already weathered years of exposure.

Why Santa Rosa Homeowners Choose Us for Shingle Preservation
Protecting the investment you have in your roof starts with choosing a contractor who can deliver a treatment no one else in the state offers. Here is why homeowners trust us with this work.
California's Only Authorized Bright Green Roof Applier
No other contractor in Santa Rosa, or anywhere in California, can sell or apply Bright Green Roof Shingle Preservation. It is a proprietary treatment that extends asphalt-shingle life by up to ten years per application and inhibits the algae and lichen that age roofs prematurely. That authorization comes directly from the manufacturer, and it is exclusive to our crew statewide.
PWNA-Certified for Roof Work
We are the only PWNA-certified exterior cleaning contractor in the Santa Rosa area, a designation that verifies our training, chemical handling standards, and commitment to industry-leading methods. That certification covers the roof cleaning category, which is the required first step before Bright Green Roof can be applied, so every phase of the job falls under the same professional standard.
Photo-Documented from Start to Finish
Every shingle preservation job in Santa Rosa is photo-documented through our Company Cam system. You receive a complete visual record of the work, before, during, and after, alongside your invoice. Because the treatment goes on as a clear coating, that photo record is your verification of what was applied and where.
California Licensed, Bonded, and Fully Insured
We hold an active California Contractor’s License (CSLB #1127739), carry a $2 million insurance policy, and are fully bonded on every job in Santa Rosa. When someone is applying a proprietary chemical treatment to the most expensive exterior surface on your home, that level of licensing and coverage is the baseline your property deserves.
Free Roof Assessment and Estimate
We provide free estimates over the phone for every service we offer in Santa Rosa. For shingle preservation specifically, the estimate includes a roof-age assessment that determines how many applications your roof can benefit from, up to three over its remaining life. That assessment alone gives you a clear picture of the protection timeline before any commitment.

How Our Shingle Preservation Treatment Works
1
The Free Estimate and Roof-Age Assessment
Call or reach out with your property details. We provide a free estimate, and for shingle preservation, we go a step further: we assess your roof's age, current condition, and growth severity to determine how many applications it can realistically benefit from. A roof between five and twelve years old can receive up to three applications over its life; an older roof can still benefit from at least one. You receive a written estimate through Housecall Pro with full terms and conditions before anything is scheduled.
2
Approval, Scheduling, and the On-My-Way Notification
Approve the estimate online and the job is booked. On the day of service, you receive an "on my way" notification so there are no surprises. If roof cleaning and shingle preservation are booked together, both are handled on the same visit.
3
The Soft-Wash Roof Cleaning
Bright Green Roof is applied to a clean roof surface, so the cleaning comes first. Our crew performs a standard soft-wash roof cleaning: SH-based chemistry delivered at low pressure through our tip-regulated soft-wash system, which eliminates algae, lichen, and moss at the root without stripping the granules that protect the shingle mat. Safety harnesses, G-clamps, GOAT anchors, pitch hoppers, Cougar Paws pads, and specialized roof boots are used throughout.
4
Bright Green Roof Application
Once the surface is clean, the Bright Green Roof Shingle Preservation treatment is applied using the Bright Green Roof authorized application system. The product is USDA-approved and biodegradable, and application takes approximately one to two hours following the cleaning. What goes onto the roof is a clear protective coating that seals the shingle surface against future biological colonization.
5
Photo Documentation and Certificate of Application
Before, during, and after photos are captured through Company Cam and attached to your invoice. A certificate of application is available upon request, documenting that the treatment was performed by an authorized contractor using the genuine product. Homeowners use these certificates for insurance records, home sale documentation, and long-term warranty tracking.
6
Walkthrough and Invoice
Our crew reviews the finished work with you once the treatment is complete. The invoice is issued alongside the full photo documentation, and any questions about the application or next steps are answered on the spot. If anything does not meet your expectations, we address it before we leave.

Frequently Asked Shingle Preservation Questions
How long does the shingle preservation treatment last?
Each application of Bright Green Roof extends asphalt-shingle life by up to ten years. The treatment can be applied up to three times over a roof’s lifespan, which means a single roof could gain up to 30 additional years of service life with proper maintenance. The ideal window for maximum benefit is between five and twelve years of roof age, since that leaves enough remaining life to receive all three applications.
Can the treatment be applied to an older roof?
Yes. An older roof can still receive at least one application, adding up to ten years of protection. During the estimate, we assess your specific roof and give you an honest answer about how many applications it can realistically benefit from. The goal is always to maximize the value of whatever time the roof has left.
Is the shingle preservation treatment safe for my roof and landscaping?
The Bright Green Roof product is USDA-approved and biodegradable, formulated to be safe for application on residential asphalt shingle roofs. The more active chemistry comes from the soft-wash roof cleaning that precedes the treatment, which uses SH-based cleaning solution. During that cleaning step, we pre-rinse and post-rinse all surrounding landscaping as part of our standard process to protect plants, grass, and ground cover throughout the visit.
Do you provide a certificate of application?
Yes. We provide a certificate of application upon request for every Bright Green Roof treatment we complete. The certificate documents that the treatment was applied by California’s only authorized applier using the genuine Bright Green Roof product. Homeowners use these certificates for insurance documentation, home sale records, and warranty tracking.
